Danger by weather (FWI30-days) in the European Wildfire Risk Assessment

Days with high-to-extreme fire danger by weather (FWI ≥ 30) - uncertainty aggregation of the model’s runs: median value [preliminary prototype approximation].
The maximum extent of possible values ranges from 0 to 1 (100 %), continuous values, so that the data satisfy the array-based semantic constraint ::proportion:: (semantic array programming).
In each spatial cell c, the variable is expressed as percentile (%), i.e. as percentage of the other cells whose value is less than in c.

Layer name : Danger by weather (FWI30-days)
Layer group: Danger
Layer unit : Percentile (%)
CSV file   : var-danger-FWI30_unit-dimensionless.csv
Projection : the native geospatial projection is EURO-CORDEX
             (https:euro-cordex.net).  European grid of the Coordinated
             Regional Climate Downscaling Experiment (CORDEX) by World Climate
             Research Programme (WCRP), https://purl.org/INRMM-MiD/z-THSLFEYQ .
             The standard grid EUR-11 is used (grid cell resolution of
             approximately 0.11 degrees, or about 12.5 km).

             Available reprojection information for WGS84
             and Lambert Azimuthal Equal-Area projection (ETRS89-LAEA).


CSV fields:
- id                        : unique id of each EURO-CORDEX cell.
- lon-1, lon-2, lon-3, lon-4: longitude (WGS84 projection) of each corner
                              in the ‹id›-th EURO-CORDEX cell.
- lat-1, lat-2, lat-3, lat-4: latitude (WGS84 projection) of each corner
                              in the ‹id›-th EURO-CORDEX cell.
- x-pos, y-pos              : position of the ‹id›-th EURO-CORDEX cell
                              in the EURO-CORDEX matrix.
- the last column lists the values of the variable (NaN: missing data).


A GeoTIFF version of the CSV file is also enclosed, rasterised in ETRS89-LAEA.  Please, note that the EURO-CORDEX spatial cells (grid cell resolution of approximately 0.11 degrees, or about 12.5 km, fully described in the CSV file) remain the reference mapping unit even for the GeoTIFF reprojected version, although for reprojecting this version in ETRS89-LAEA the native EURO-CORDEX cells were subject to a technical upsampling in contiguous clusters of pixels with higher resolution.
